| Research Abstract |
This study proposes new vibration control methods using neural oscillators. One of the methods is for active mass dampers and the other one is based on harmonically varying damping for semi-active dampers. In biological study, Central Pattern Generators(CPGs) consisted of the neural oscillators in bodies playing a significant role in the walking have been learned over the last few decades. In this study, the algorithm is installed into the controller for the active mass damper requiring robustness and stroke limitation, and is tried to embed into the controller for the semi-active damper. Moreover, this study shows an evaluating method of synchronization between a structure and the CPGs installed in the controller using phase reduction theory. In addition, this study demonstrates application of the harmonically varying damping to MR dampers and the effect of the harmonically varying damping on a coupled structure in parallel with the variable damper.
